Specification of Letters Patent.

Patented July 29, 1919.

Application led November 20, 1918. Serial No. 263,345.

To all ywhom 'it may concern Be it known that I, FRANCIS LEE STUART, residing in District of Columbia, have invented certain new and useful Improve ments in Conveyers, of which the following is a specification.

This invention relates to apparatus for carrying material brought from a distance by a main conveyer'belt to a pile or other storage, and also to apparatus for gathering material and depositlng it upon a -conveyer which carries it to a distant point, and provide improved means `for operating the apparatus with greateracility andwith iii-- creased power.

The apparatus herein shown and described is similar, in many respects, to the apparatus shown, described and claimed-.in my application for Patent No. 237 ,880, filed June 3, 1918, wherein the apparatus is con.- structed to either deposit material received from a main conveyer belt or to gather material from apile or place of storage and deposit'it on a main conveyer belt. In.l the power for operating the mechanism when gathering or reclaiming material is applied to the inner end nism and inasmuch as thegatheringdevices are located at a considerab e distance from such power mechanism there is, attimes, unduestrain on the ap is sometimes insuliiclent.

According to my present invention, I apply the power for moving the' gathering devices at thepouter end or at the outer portion of the reclainfer. For this purpose I preferably employ a tractor ofthe caterpillar type and provide means for steering such tractor to enable it to direct the gathering mechanism in any desired direction.

My improvements 'are illustrated in the accompanyin drawin in which- Figure 1 sows a si e elevation of apparatus embodying my improvements, in which meansl is provided for receiving material from a main conveyer belt and deplositing it in a place of storage, combined wit means the object of thenventionpis to of gathering of the reclaiming mecha-- paratus and the powerV4 claimer.l

Fig. 21 is a plan view of the parts shown in Figs. 19 and 20.

In Figs. 1 and 2 of the drawings, I have.

shown a main conveyer belt A, provided with a loop or tripper A which delivers through hoppers orchutes B to a belt C, carried by the -frame D 0f claiming conveyer. The belt C is motor driven, as indicated at' E. Said belt may deliver through ahopper F to the veyer belt A, but when said reclaimer belt is moved in the opposite direction it may deliver material supplied by the hoppers B to a place for storage.v The reclaimer is supported by a frame G, carried by a` turntable H, supported on the-truck J, which is as indicated at y' and traverses the track pled at KI to another truck L-which supports the loop Af of the main conveyer belt. The turntable maybe operated by a motor M and the reel-aimer may be tilted, i. e., raised and lowered by motor mechanism N. The mechanism thus far described is similar to that shown in my application for Patent No. 237,880, liled June 3, 1918 above mentioned and to which reference is made for further details. f

f On the outer end of the boom conveyer frame D I mount a gathering device of suitable construction.

In Fig. 1 I have shown what is ordinarily called a scraper plow O mounted in a frame P and carrying a belt p which receives material from the plow O. and deliversy it through a hopper Q, to the belt C. This hopper Q is pivoted -at g'and maybe raised and lowered when required. The belt p is driven by suitable connections indicated at p. The frame P, to `which the scraper plow is attached, is supported on a tractor R preferably of the caterpillar type and which is more clearly shown in Figs. 19, 2O and 21 of the drawings,

In Figs. 3 and 4 of the drawings I have shown a slight modication. Many of the parts are similar to those hereinbefore A described and are similarly'lettered. In this the reclaimer frame ismade endwisevdjustable in a manner similar to that sh 256,67afi1ed oct. 3,1918.

In Fig. 3, -S indicates motor-driven mechanism for giving an endwise movement to the reclaimcr D; s indicates motor-driven mechanism for driving the truck; s`indi cates motor mechanism for tilting the reclaiming mechanism, and s2i indicates motor mechanism `for operating `the turntable; otherwise the apparatus is similar to that hereinbefore described and said. last mentioned mechanism is similarfto that shown in my application for Patent filed Oct. l3, 1918 above mentioned.l In Fig. 3 thefgathering mechanism is slightly different from In this case instead of employing a scraper plow O, a plow Ov is shown which is adapted to move endwise into the Vmaterialfbut as indicated in Fig. 3f a scraper plow O2 maybe substituted for the plow O inthe apparatus shown in Fig. 3.

'In Figs. 5-8,` inclusive, I have merely shown the gathering .mechanism herenbefore described on a large scale in order that l'the details oi construction may be more fully understood.

- It will be observed, by reference to Figs. 5 and 6, that the frame P isso mounted on the outer end of the frame D that it may be detached therefrom if desired, as indicated at a', and it willalso be observed that the frame P -is supportedby a tractor R, which is preferably of the caterpillar type and is constructed and operated in the manner most clearly shown in Figs. 19, 20 and 21. As there lillustrated the tractor comprises a truck t which is pivotally connected with the frame P at t. Two tractor belts U are-employed. These may be of any desired construction and may be suitably supported in the truck. They are driven by a motor V which is geared, as indicated at c, to a shaft fv, which is geared at o2 to a worm wheel c3. wheel is adapted to be connected with either one of the tractor belts -U or with both of them by suitable clutch mechanism. The clutch mechanism W on one side is geared to one of the tractor belts and the clutch mechanism W on the opposite side of the wormv wheel is geared to the other tractor belt. By means of suitable operating mechanismY the clutch may be operated to connect both tractor belts with the driving mechanism or connect only one of the tractor belts with said driving mechaown in my application for Patent N o.

case the tractor belts' U yso ' Larmes nism, so thatthe apparatus may be steered in the desired way. r.By employing mecha nismof the kind described the reclaimcr may be moved longitudinally of itself or moved forward at any desired angle -with vreference to the main nveyer belt or it may be swung in thea'rc of a circle about the axis of the turntable as a center.

. When apparatus of the .kind illustrated in Figs. 3 and 4 is employed, the mechanism maybe operated in the -.manne'r indicated in Fig. 9, where it will beiobserved thatl the truck J is moved longitudinally over the main conveyerbelt and the reclaiming conveyer is projected longitudinally' of 'itself or at an angle to the main conveyer'belt to gather material from the pile Z. In this are arranged parallel with the longitudinal axis of the reelaimer.

In Fi 10 where a scraper plow -is employed t e tractor is arranged transversely move the reclaimer in various ways and 'atY various angles, as partially indicated in Figs. 9 and 10, and by providin the 'tractor with the steering mechanism escribed the movement of thev gathering mechanism may be controlled at will.

As before stated,"the apparatus may be employed-tostore material or to gather it. Fig. 11 illustrates how apparatus of the kind shown in Fig. 3 maybe employed to deposit material-on a pile and also, by

dotted lines, how the same apparatus maybe used to gather materialfrom the pile.

claimer.

In Fig. 15 I have-indicated how my improvements may beapplied to an apparatus which is similar: to that hereinbefore described but in which no provision is made forgiving an eudwise movement to the re- Fig. 15 shows how vthe material may be deposited on top of the pile, while Fig.I 16 shows how thesaine apparatus may be used for gathering material.`

In Fig. 14 I havef'shown a modified way of connecting the frame P with the frame D of the reclaimer. In this case a pivotal connection is made at v2 but this feature is not claimed herein.

Another modification is shown in Fig. 18 wherein the frame P is detachably connected at d with the frame I) and this connection may be also a pivotal one. ISimilar subject matter is shown in my application for Patent No. 258,355, filed Uct. 16, 1918 in which- I have claimed, among other things, re-

claiming apparatus comprising a reclaiming conveyer sup orted at one end to swing about a vertical axis and provided at its outer end with a gathering section which is pivotally connected with the main portion of said reclaiming conveyer, and a tractor for supporting and moving said gathering section about its pivotal connection with the reclaiming conveyer, and I have also claimed in such application the subject matter just referred toV in which .detachable connections are rovided between the gathering section and t e main portion of the reclaimingi` conveyer.

he principal feature ofnovelty "claimed in this application is' the means for apply,

ing power directly to the outer portion of the reclaimer and the means for steering the tractor mechanism.

It is also evident that by properly operating and steering the tractor the truck J to which the reclaimer is pivoted may be moved coincidentally or simultaneously with the reclaimer. It may be held stationlarywhile the reclaimer is swung in the arc of a circle, or when the reclaimer is set at an angle to the main conveyer belt the tractor may be so steered and yoperated as to move the truck forward or backward while the gathering end of the reclaimer enters a ile at various angles progressively..

en the reclaiming. apparatus .is of the kind shown in Figs. 3 and tand also in Fig. 9 of the drawings, the tractor may be employed for giving anendwise movement to the reclaimer in addition to the movements liereinbefore explained.

The tractor may be used to operate the reclaimer tomove it endwise or to swing it about its pivotal connection with `the truck J either alone or in connection'with the m0- tor mechanism hereinbefore described for giving such movements to the reclaimer, but the use of a tractor on the outer portion of a reclaiiner is .important when reclaiming inasmuch as it Vaffords means for giving avoids the 'strain which would otherwise be incident to the operation of the mechanism.
